Fix the build on MacOS

Three things kept it from building there:

- librt was linked unconditionally, MacOS has those functions in its system
  library and no librt to link
- -march=native and -mtune=native are not accepted by the compilers on Apple
  Silicon. They are dropped there, the speed of the training is not what MacOS
  is used for here
- homebrew installs into /opt/homebrew on Apple Silicon, which was in neither
  the include nor the library path

STATIC_DEREKO2VEC stops with an explanation on MacOS now instead of failing at
link time, as there are no static system libraries to link against.

Verified on Linux that nothing changes: -march=native and -lrt are still used,
the build and the training test pass. The MacOS paths themselves were only
exercised by forcing APPLE, a real build there has not been tried.
